Alright. Ive just found a block thats in my budget for a killer price.

First Ill let you know about my head, its a D16a6 head, fully built all internals but Im worried about clearance and compression with this so that what Ill mention, the head is milled .040 thousand, 1mm oversized titanium valves and running a delta 272 cam (aggressive)

Now the block

D16y7, SRP 9:1 comp pistons, Crower billet rods, balanced and micropolished d16y7 crank, .020 overbore.

Now if you guys would be able to tell me what compression I would be running (estimate ) with a cosmetic head gasket.

Also if you could give me any clearance advise, please dont say clay it, because Im not gonna buy it if theres a chance of slapping

Any other advise appreciated. Car will be boostin 16-18psi daily on TurboEdit

Thanks

 

i HIGHLY doubt that you will have valve piston contact. the head i am using is milled the same amount and i am using P29 pistons with RM cam, no contact as long as i keep the cam turning along with the crank.
what happened to your NA build idea?

i hope you have been reading about the perils of using titanium parts in your head

seems its a very abrasive metal

 

Still have the high comp project moving quick ****, thats going to be the car I run laps on teh track with

THis boosted Crx is my daily POS

Never heard anything about titanium parts being bad. My springs are also dual titanium

However though it wears down easier, it is not as brittle as steal so it can handle higher lift........Kinda of a ying and yang situation!</TD></TR></TABLE>

 

i`ne been runnin the same portflow retainers in my setups for about 3 years and have had no problems. i even pulled them outta one head and put them in another. titanium ret`s and portflow inner and outter springs. maybe im just lucky

 

its cause were up until 6am

free bump for us

 

piston dimensions?

with know piston dim i can tell u exactly what the cr will be.


Compression Height, (mm) and dish/dome and it's height (mm).

 

added: also.. so far it looks to be close to 9.1:1 c/r.

I used http://www.knology.net/~jediklc/D.htm

 

hmm wish I had those #'s

as long as Im 9:1-9.5:1 Ill be happy

And obviously dont want **** to slap eachother

 

call srp and ask for the dimensions

 

Just waiting on the specs from the seller

But still need clearance opinions

 

this block is defientely mine if I want it, need some help
